Kubernetes.
A real cluster on a small server.
Run Kubernetes on a single VPS with K3s: install it, deploy an app with HTTPS and persistent storage, fix Pending and CrashLoopBackOff pods, and deploy from Git with Flux.
K3s is a lightweight Kubernetes that fits on a single VPS. It is a good way to learn Kubernetes and to run workloads that are built for it, though for one or two applications Docker Compose is simpler.
These guides take you from installation to a deployed app with certificates and storage, then to debugging and Git-driven deployment with Flux.
